So, first time user: Had several fire bases set up, just got them supplied and ready to go. Not knowing how the mod would work, I assumed I would click on the nest I wanted gone, and it would take them out. One click, and (as documented), the system lagged out for a few seconds. The first non-lagged frame showed a message with 8,000 new fire missions, and the map was filled with fireflies moving in every direction as dozens of howitzers from several bases started firing at every nest possible.
It's a bit more scorched earth than I expected, but I suppose I should have taken the description literally
